SMUT-MACI-IINE.

Specification of Letters Patent No. 3,301, dated October 12, 1843,

To all whom it may concern: 1

Be it known that I, EDWARD HOWARD, of Fredonia, in the county ofChautauqua and State of New York, have invented a new and usefulimproved machine for cleaning wheat from smut and other impuritiescalled Howards stationary center doublecylinder smut-machine, and I dohereby declare that the following is a full and exact description of mysaid invention.

My said machine consists of three principal parts, to wit: First, themoving part, consisting of an upright shaft, eight or more heaters,supported by a revolving head attached to the said shaft below thecenter cylinder hereafter mentioned, which said heaters are connectedwith each other at the upper end by a horizontal rim or hoop, four smallwings attached to the said revolving head on the under side thereof, sixlarger wings revolving above the middle head and the drivingpulleyattached to the shaft, between the yoke and upper head. Second,the stationary center, cylinder surrounding the said shaft though notattached to it, and made fast to the middle head hereafter mentioned bymeans of iron rods or bolts and screws. Third, the outer'cylinder whichis also stationary and containing the parts above described, exclusiveof the large wings which are betweenwthe middle and upper head, whichlast mentioned head is connected with the middle head by means of postsand screws. The said machine together exhibits an upright cylindricalstructure of iron (Figure 1) about three feet and a half high exclusiveof fixtures above and below but may be made larger or smaller, the lowerhead of which (6) is made to receive and confine the ends of the castiron plates which compose the outer cylinder within the circle of araised flange (a) ,on the upper face of said head. The saidhead is sunkfrom the inner side of the cylinder to the depth of from three to sixinches (6) with an open center of from eight to twelve inches indiameter (aide C, Fig. 2). This cylinder is of equal size the wholelength and confined at the top in the same manner as at the bottom, themiddle head (cl) being flat, with a hole in the center of from nine toeleven inches in diameter, (see Fig. 1, which exhibits a quarter sectionof said head) with flanges upon the outer and inner sides (Fig. 2; P,P,) for the purpose of re ceiving and confining the upper ends of theouter and inner cylinders. The said outer cylinder is grooved orchanneled (Figs. 1

and 5) inside and outside, for the purpose of adding strength withoutweight and to form edges on the inside to assist in beating and scouringthe grain. (Fig. 5 repre sents a cross sectionof the machine.) The saidgrooves or channels run diagonally Fig. 1, 6,) from the bottom to withinabout eight inches of the topof said cylinder.

Commencing at the top ofjea-ch groove or channel and extending about onethird of the distance down the same is an aperture for opening (f,)about oneeighth of an inch wide through which some part of the dust land smut mayescape. The two heads are held together by four or more rods'or 'bolts (g,) passing through their edges outside Above the saidmiddle head and about five inches therefrom is the upper head (S, theupper surface of which is exhibited in Fig. 3,) which is connected tothe middle head by means of four iron bolts or posts (9,) passingthrough projections (N, Fig. Through the center of this head (cl,)passes the main shaft (?I,) (see Fig. 2,) into the yoke (r, as seen inFig. 1,)

.which is screwed to the said upper head,

and which together with said head helps to support and steady the saidmoving part of the machine. The said moving part of the machine (seeFig. 2, which represents a longitudinal section of the machine tothemiddle head inclusive) consists of an upright shaft resting and turningin a steel box (j,) supported by a screen (70,) with which the shaft maybe raised or lowered; attached to which shaft is the revolving head (Z,)(Fig. l, repres-entsthe lower surface of said head) to which the boatersare attached by bolts or screws (Fig. 4). The heaters (m,) are ofwrought iron about one and one fourth inches wide and of such form andshape as is judged best and are secured at the top by an iron rim orhoop (12,). (See Fig. 8, which represents a heater with a section of therim.) Under the head to which said heaters are attached arethree or foursmall wings (0,) for the purpose ofadding to the current of air upward.Also attached to the said shaft between the middle and upper heads arethe wings (A, A,) (Fig. 6, represents a cross section of said wings,)six or more .in number about four inches wide and extending outward farenough to sweep the whole space inside of the posts (q, 51, see Fig. 1).The shaft passes upward through the upper head (8,) above which isattached to it the driving pulley (t,) about eight inches in diameterupon which a board is placed to drive the machine above this pulley theend of the shaft is supported by the yoke (r,) the ends of which arebolted or screwed to the said upper head. The shaft with the heaters andwings is capable of making about six hundred revolutions per minute.Within the beaters, and outer cylinder above described is the centercylinder (see Fig. 2, a). Fig. 5, represents a cross section of saidcylinder) confined at the top by the flange P, P,) on the middle headand fastened'to saidhead by means of the iron rods (V, V,) which passesthrough the lower head of said cylinder and through ears or projectionson the inside of said middle head. (Fig. 7 represents a quarter sectionof said middle head.) The body of said cylinder is of iron with groovesor channels corresponding to those on the outer cylinder (see Fig. 5,)and with eight or more apertures (Fig. 2, WV, WV,) between said groovesor channels and the top of the said cylinder each from three to fourinches square to allow the smut and dirt to pass off through the centerof the middle head as hereafter mentioned. The upper end of said centercylinder is entirely open as shown at X. (See Figs. 2, and 7 But thelower end is secured by a head (Y, Y, see Fig. 2,) through which themain shaft passes. This head is to give strength and steadiness to saidcylinder and to force the air between the two cylinders which mightotherwise pass through the center.

The wheat is conveyed into the said machine by a hopper through a holein the side of the outer cylinder (Z) below the top of the heaters herecoming in contact with the heaters it is freed form dirt and smut thelatter being pulverized and the clean wheat runs out through the openspace in the lower head (0,) while a strong current of air produced by.the swift revolution of the wings and heaters rushes up through the sameopen space and carries all the smut and dirt through the squareapertures near the top of the center cyinder, (W, WK) thence through themiddle head (X) where it is finally blown away by the wings (A, A.) Butif thought proper the apertures or openings in the grooves or channelsof the outer cylinder .(f) may be closed and then by incasing the spacebetween the middle and upper heads around the wings (A, A,) with sheetiron and placing a tube therein the smut and dirt may be blown away outof the mill.

lVhat I claim as my invention and desire to secure by Letters Patent is-The combination of the revolving frame or boaters with the inner andouter stationary cylinders constructed and operating as above set forth.
